Key Insights about IRS Form 1099-S

Report the sale or exchange of real estate, including land, buildings, condos, co-op stock, and standing timber, when total consideration is $600 or more.
For the 2026 tax year, transferor copies are due February 16, 2027; paper filing, March 1, 2027; e-filing, March 31, 2027.
New for 2026: digital assets used to pay for real estate are reported in Box 2c and Boxes 8a to 8d, and Box 2 is now split into 2a, 2b, and 2c.
Form 1099-S qualifies for an automatic 30-day extension, unlike Form 1099-NEC or Form W-2.

What is Form 1099-S?

Form 1099-S, Proceeds From Real Estate Transactions, is an IRS information return used to report the sale or exchange of real estate. It is generally filed by the person responsible for closing the transaction, such as a settlement agent, attorney, or title company.

As the filer, you are responsible for filing this form with the IRS and furnishing a copy to each transferor (seller).

Form 1099-S covers the sale or exchange, for money, debt, property, or services, of any present or future ownership interest in:

Improved or unimproved land, including airspace
Permanent structures, including residential, commercial, and industrial buildings
Condominium units, with their fixtures and common elements
Stock in a cooperative housing corporation
Non-contingent interests in standing timber

Form 1099-S also reports timber royalties paid under a pay-as-cut contract.

A reportable sale does not have to be taxable. For example, the sale of a main home can be reportable even if the seller can exclude the gain under section 121. Transfers to a corporation under section 351 and land contracts are also reportable.

What counts as an ownership interest?

Ownership interests include fee simple interests, life estates, reversions, remainders, and perpetual easements. Leaseholds, easements, and timeshares count only if their remaining term, including renewals, is at least 30 years on the closing date. An option to buy real estate is not an ownership interest.

Who must file Form 1099-S?

The person responsible for closing the transaction must file Form 1099-S. When a Closing Disclosure lists a settlement agent, that agent is the filer.

If no Closing Disclosure is used, or two or more are used, the filer is the first of these who applies:

The buyer’s attorney who is present at delivery of the proceeds or who prepares or reviews the transfer documents
The seller’s attorney, under the same conditions
The title or escrow company most significant in disbursing the gross proceeds

If no one is responsible for closing, the filer is, in order: the mortgage lender, the seller’s broker, the buyer’s broker, and then the buyer.

Designation agreement: parties can sign a written agreement at or before closing naming who will file. Each signer keeps the agreement for 4 years. Only one person files, and only one Form 1099-S is filed per transferor.

Employees and agents: when an employee, agent, or partner takes part in a transaction, the employer, principal, or partnership is the filer.

Which real estate transactions are exempt?

These transactions are not reportable, though you may choose to report them:

Exception	Condition
Principal residence sale	$250,000 or less ($500,000 if married), with a signed seller certification that the full gain is excludable under section 121
Corporate and government sellers	The transferor is a corporation, a governmental unit, or an international organization
Exempt volume transferors	Sellers of at least 25 items to 25 buyers held for resale, with a certification
Non-sales	Gifts, bequests, and refinancings unrelated to an acquisition
Debt satisfaction	Foreclosures, transfers in lieu of foreclosure, and abandonments
De minimis	Total consideration under $600

Sales of natural resource interests, crops, burial plots, and unaffixed mobile homes are also not reportable when unrelated to a sale of reportable real estate.

For the residence exception, you can collect the certification up to January 31 of the year after the sale and must keep it for 4 years. If you don’t get it, you must file.

What’s New on Form 1099-S for the 2026 Tax Year?

Form 1099-S has an important reporting update for the 2026 tax year. Digital assets received as consideration in the sale or exchange of real estate are now specifically addressed on Form 1099-S.

Digital asset proceeds: Box 2c is used to report the gross proceeds attributable to digital assets received or to be received as consideration for real estate.
Digital asset details: Boxes 8a through 8d capture the digital asset identifier, name, number of units, and date received or to be received.
Updated instructions: The December 2026 Form 1099-S instructions provide specific guidance for reporting real estate transactions involving digital assets.

Gross proceeds are split into three boxes:

Box	What it reports
2a	Total gross proceeds, the sum of Boxes 2b and 2c
2b	Total cash gross proceeds, including notes, assumed liabilities, and cash from a digital asset payment processor
2c	Digital asset gross proceeds, the fair market value in U.S. dollars of digital assets received or to be received

New digital asset detail boxes:

Box	What it reports
8a	Digital Token Identifier (DTI) code from the DTIF registry, or 999999999 if not registered
8b	Full name of the digital asset
8c	Number of units received, to 18 decimal places
8d	Date received, in MM/DD/YYYY, or blank if received on various dates

The FIRE e-file system retires December 31, 2026, and IRIS becomes the required filing system afterward. See how TaxBandits helps with the IRIS transition

Common Form 1099-S filing mistakes to avoid

Reducing proceeds by selling expenses. Gross proceeds are not reduced by commissions, deed preparation, advertising, or legal fees.
Leaving out assumed debt. A liability the buyer assumes, or takes the property subject to, counts as cash and belongs in Box 2b.
Including personal property. Separately stated cash for items like rugs or appliances is not part of cash gross proceeds.
Missing digital asset consideration. For 2026, if the contract provides for payment in digital assets, report the value in Box 2c and complete Boxes 8a to 8d.
Using the old box numbers. For 2026, the buyer’s real estate tax is Box 4, the property or services checkbox is Box 6, and the foreign person checkbox is Box 7.
Filing more than one form per seller. Only one person files, and only one Form 1099-S is filed per transferor.
Relying on an incomplete residence certification. The certification must include no nonqualified use after 2008 and a statement that the full gain is excludable.
Like-kind exchanges with no proceeds. Enter -0- in Box 2a and check Box 6.

The person responsible for closing, usually the settlement agent listed on the Closing Disclosure. Parties can also name a filer in a written designation agreement.

Only when paper filing. Form 1096 is not required for e-filing.

File a corrected Form 1099-S as soon as the error is identified.

If your seller has questions about their 1099-S

Sellers often contact the closing agent once their copy arrives, especially first-time home sellers. Clear answers reduce correction requests during filing season.

Not necessarily. Form 1099-S reports gross proceeds, not gain. A seller who qualifies for the home sale exclusion under section 121 may owe no tax, but may still need to report the sale.

Box 2a shows gross proceeds, generally the sales price. It isn’t reduced by commissions, closing costs, or mortgage payoffs.

It shows real estate tax the seller paid in advance that is allocable to the buyer. The seller generally can’t deduct that portion.

If the sale was $250,000 or less ($500,000 if married) and the seller signed a certification that the full gain is excludable, the closing agent isn’t required to file.

For 2026, the value of digital assets received appears in Box 2c, with details of the asset in Boxes 8a to 8d.
